Innovative Lightweight Solutions for Sustainable Mobility

Hightech-Engineering made in Dresden (Germany)


Leading through innovation​

Creating innovative lightweight solutions to make transportation safe, efficient, and environmentally friendly – that’s our profession. Wherever transportation is needed – on rail, road, or water, in the air, or in machinery and systems – we develop the right solution for the job so you can achieve your goals faster.


Feasibility studies
Study of complex assemblies to identify lightweight construction potential

crane boom

Lightweight solutions for construction machinery can improve the load capacity and the outreach

combine harvester

Lightweight solutions for agricultural machinery can increase working width and reduce soil compaction


Lightweight solutions for commercial vehicles can, for example, increase the transport load and reduce axle loads

Ground-breaking Innovations Innovative Leichtbaulösungen



As an engineering service provider, we take a holistic approach. We assess the lightweight potential of components, make the material selection, design the components and their production in accordance with the material, and realize prototype construction and testing – all under the aspects of safety, economy, and sustainability.
